Product Description
The IS215VPROH2B is designed for turbine units (gas, steam, or combined cycle) as a dedicated emergency protection module. It belongs to the Mark VI series but focuses on overspeed, overtemperature, and emergency shutdown functions. It typically interfaces with TREG/TRPG terminal boards to trigger turbine shutdown or cut fuel/drive systems during abnormal conditions.
The module uses triple modular redundancy (TMR), with three independent VPRO boards (R8, S8, T8) that vote on outputs. If one board fails, the remaining two maintain protection, ensuring uninterrupted safety.
It is designed for rapid response, with Trip Solenoid activation time constants around 0.1 seconds. Its VME single-slot form factor allows modular installation and replacement. Its robust industrial-grade design makes it suitable for critical safety applications in turbines.
Applications
-
Gas turbine startup/shutdown emergency protection (overspeed trip).
-
Steam turbine overtemperature and bearing monitoring shutdown.
-
Combined cycle power plants as a backup turbine protection loop.
-
Offshore and onshore power plants to control turbine or compressor emergency shutdown.
-
Replacement or upgrade in existing Mark VI control racks to improve reliability.
Advantages
-
High reliability with triple modular redundancy.
-
Dedicated turbine protection for overspeed, overtemperature, and synchronization faults.
-
Rapid response with 0.1-second Trip Solenoid activation.
-
Modular installation allows quick replacement and reduced downtime.
-
Industrial-grade durability for temperatures from ‑30 °C to +65 °C.
-
System compatibility with Mark VI series controllers.
-
Easy maintenance via LED indicators and modular design.
-
Prolonged turbine life by preventing catastrophic events.
